This study integrates the lens of social influence theory, virtual communities of practice, and practicebased view into a theoretical model to understand the role of social influence in B2B virtual communities in the collaboration of innovation activities with co-creating users. Specifically, the main goal of this study is to unravel the relationships among social influence, contribution behavi...

Virtual environments and the Internet provide an important medium for interactive collaborative learning. Immersive Virtual Environments appear able to support intuitive interaction techniques and metaphors. Our Identity Authoring Approach is aimed at our multicultural global society, and allows for multiple identities / persona to be created and used as interaction metaphors by users. The appr...

In this paper we propose, firstly, a categorification of virtual braid groups and groupoids in terms of “locally” braided objects in a symmetric category (SC), and, secondly, a definition of self-distributive structures (SDS) in an arbitrary SC. SDS are shown to produce braided objects in a SC. As for examples, we interpret associativity and the Jacobi identity in a SC as generalized selfdistri...

This experiment varied whether individuals interacted with virtual representations of themselves or virtual representations of others in an immersive virtual environment. In the self representation condition, half of the participants interacted with a self representation which bore photographic resemblance to them, whereas the other half interacted with a self representation that bore no resemb...

Although there’re studies that investigate the factors affecting the intention to purchase virtual items in virtual worlds, most of these studies focus on the technological factors that enhance user experience (e.g., social presence) while pay less attention to the social factors that facilitate user participation and involvement (e.g., user engagement). To fill this gap, taking MMORPGs as a ki...

In this paper, an equivalent ‘virtual’ SIMO (Single Input Multiple Output) radar representation of the MIMO radar system is established which enables the analysis of the full MIMO system geometry. Analytical expressions are derived to describe the key geometrical properties of the virtual array’s manifold, which fully characterises the entire transmit-receive system geometry. A new family of su...

A commonly used virtual machine monitor (VMM) allows multiple operating systems to share physical hardware resources as virtual resources in a safe manner. It provides a strong isolation mechanism between virtual machines (VMs). In this paper, we state the importance of ID management for a securitypurpose VMM system to enforce security policy on an end-user environment. We present a design of a...
